Wastewater surveillance has been widely used to track the prevalence of SARS-CoV-2 in communities. Although some studies have investigated decay RNA wastewater, understanding about its fate during wastewater transport real sewers is still limited. This study aims assess impact sewer biofilms on dynamics concentration naturally contaminated (raw influent without extra virus/gene seeding) using a...

In this paper, the problem of large pure bending deformations of membrane is considered. The membrane is a sector of torus with a closed cross-section. This membrane is called a curved tube for short. We consider the homogenous, incompressible, isotropic and hyperelastic material. The external load is a constant pressure and bending couples acting at the edges. The equilibrium equations reduce ...

A tough and thin double-network gel membrane containing amino acid ionic liquids as a CO2 carrier exhibited superior CO2 permeability and stability under pressurized conditions.
